Yes and no. The skirmish lines indicate where the skirmish battle is happening as in the case of the British who group their skirmish companies into battalions, they fight in open order with their skirmish line thrown out ahead of them, whereas the French are using their Voltigeurs as a screen for each battalion.

There is some sources that suggest the French were doing the same thing as the British and grouping their volts into battalions, and I may start doing that as I start to do more stuff in the later Peninsular period.

The Skirmish battle will happen anywhere between 400 to 500 paces beyond the formed troops depending on if there are rifles available
